Integral column for projection equipment

Abstract

The invention provides an integral column for projection equipment. The integral column comprises a mounting frame and an integral column body; the mounting frame movably penetrates through a shell ofthe projection equipment through installation holes, and frame plates are fixedly arranged on the two sides of the mounting frame; through holes are formed in the frame plates, and threaded holes areformed in the positions, corresponding to the through holes, of the shell; the mounting frame is installed on the shell through bolts penetrating through the through holes and the threaded holes, thebolts are sleeved with compression springs, and the compression springs are located between the frame plates and the shell. Installation frames are arranged on the two sides of the bottom of the mounting frame, and bearing seats are arranged on the installation frames; and the integral column body is rotationally arranged between the two bearing seats in a penetrating mode. A first gear is pivoted in the mounting frame, a slotted hole corresponding to the first gear is formed in the bottom of the mounting frame, and the bottom of the first gear protrudes out of the bottom of the mounting frame from the slotted hole; a second gear is arranged on the outer wall of the integrating column body and is in engaged transmission with the first gear; the vertical adjustment and rotary adjustment ofthe integral column can be achieved, the integral column can be conveniently adjusted to a proper position, and a better projection effect is provided.

Description

technical field [0001] The invention relates to the field of integrating columns, and more specifically, to an integrating column for projection equipment. Background technique [0002] The light engine of the existing projector includes an integrating column, which can make the incident light undergo multiple total reflections in it, so that the outgoing light can be uniformly distributed. [0003] In the process of actually assembling the integrating column into the optomechanical housing, due to the manufacturing error of the integrating column or the optomechanical housing itself, as well as the assembly error generated during assembly, it is easy to make the actual assembly position of the integrating column deviate from the original preset. set location. [0004] In order to correct the position of the integrating column, an adjustment device is usually provided on the housing of the optical machine, so that the position of the assembled integrating column can be fine...

Problems solved by technology

[0004] In order to correct the position of the integrating column, an adjustment device is usually provided on the housing of the optical machine, so that the position of the assembled integrating column can be fine-tuned to optimize the image output performance of the optical machine; however, the existing integrating Most of the columns can only achieve vertical height adjustment, and the adjustment dimension is limited, which cannot provide better projection effect
